HeapByteBufferR

public class HeapByteBufferR extends HeapByteBuffer
A read-only HeapByteBuffer. This class extends the corresponding read/write class, overriding the mutation methods to throw a {@link ReadOnlyBufferException} and overriding the view-buffer methods to return an instance of this class rather than of the superclass.

Fields Summary

HeapByteBufferR(int cap, int lim)

		// package-private

	this.isReadOnly = true;
HeapByteBufferR(byte[] buf, int off, int len)

 // package-private







	super(buf, off, len);
	this.isReadOnly = true;
protected HeapByteBufferR(byte[] buf, int mark, int pos, int lim, int cap, int off)








	super(buf, mark, pos, lim, cap, off);
	this.isReadOnly = true;
